I have a Dell Inspiron 9300 with a radeon card, using latest rawhide.

As I mentioned yesterday, I had seen these errors a few months ago but
they went away.

Yesterday I had 3 NMI's in the space of about 4 hours. In each case, I
had just selected a menu or submenu and it had just finished being
drawn to the screen.

I turned off compiz and haven't had an NMI all morning. If you're
using compiz you might want to give that a try.

That does tend to point to a buggy driver.
